![]() Signal '11' is recommended when terminating the process since it will generate the crash log which can be observed later with the command ' diag debug crashlog read'. “45” stands for a number of processes displayed. “1” stands for refreshing period in seconds Higher number of sessions lead to higher memory usage.įortiGate performance data sheet also defines the maximum number of sessions firewall can handle.ģ) By running in CLI ' diag sys top 1 45' it is possible to find memory usage per process instance. Session table is stored in memory as well. If the amount is vastly different between last 1 minute and last 30 minutes, this might indicate a traffic spike. If it is too close, the device is likely to be overloaded and there is a sizing issue. The unit is either getting overloaded or there is a memory leak in some process/kernel or there is a lot of cached memory.Ĭheck the amount of traffic and compare it to the data sheet (throughput section). In case used memory is more than 75%, this may indicate that a further check may be required. Run the command above a few times and compare patterns of memory usage, throughput and number of sessions.Ģ) Check total memory usage on the output. Memory: 2004540k total, 586528k used (29%), 1418012k free (71%)Īverage network usage: 1 / 0 kbps in 1 minute, 0 / 0 kbps in 10 minutes, 0 / 0 kbps in 30 minutesĪverage sessions: 25 sessions in 1 minute, 25 sessions in 10 minutes, 25 sessions in 30 minutesĪverage session setup rate: 0 sessions per second in last 1 minute, 0 sessions per second in last 10 minutes, 0 sessions per second in last 30 minutes The only downsides of the software are that it won’t work on Linux-based systems and can’t perform firmware updates.This article describes general actions which could be taken and which information should be sent to Fortinet Support in case of unexpectedly entry of the unit into Conserve Mode, the unit is out of memory.ġ) Run the command in CLI ' get system performance status' the output will look similar to the sample below:ĬPU states: 1% user 0% system 0% nice 99% idle 0% iowait 0% irq 0% softirqĬPU0 states: 1% user 0% system 0% nice 99% idle 0% iowait 0% irq 0% softirq You can also use it to do some minor adjustments of power management and notifications. You can check firmware updates, port details, buffer size, read and write speeds, power consumption, and S.M.A.R.T information. Of course, general information is also provided. It is one of the few free utility tools that have the ability to gather accurate data for both types of storage drives and work with drives from all manufacturers. Crystal Disk InfoĬrystal Disk Info is open source software which can give you health and temperature information for your SSD or HDD. Last but not least, if you aren’t pleased with the diagnostics results and your benchmarks, you can always optimize your Samsung SSD for your current OS with the OS Optimization feature in Samsung Magician. This will improve the overall performance, especially the read speed numbers. This mode can make use of 1GB of your system’s DRAM as cache for hot data or frequently-accessed data. What Samsung Magician offers through its RAPID mode makes it worth it even more. ![]() Optimization and diagnostics are just the tip of the iceberg.
